A magnetic rotational position sensor for sensing the rotational position of a control shaft about a first axis over a definable range of rotation is disclosed. The magnetic rotational position sensor includes a magnetic circuit formed by a peripherally interrupted outer pole piece defining an air gap and a magnet disposed within the air gap to generate a magnetic field. The magnetic circuit is adjoined to the control shaft to synchronously rotate the magnetic field about a second axis. A magnetic flux sensor is disposed within the magnetic field to sense the rotational position of the control shaft as the control shaft is rotated about the first axis over the definable range of rotation.
